It stands to reason it will eventually happen, but compared to a satellite there is a much lower liklihood that as an individual you will experience harm because of such an update. Some mitigating factors: - they can do slow releases. So if a serious anomaly does occur it is unlikely to be with your car. - the conditons of space make errors much more catosptrophic. Although I can imagine similarly catosptrophic scenarios with a car, there are also more opportunities to safely rectify the situation (like the car pulling over and refusing to drive if things are not ok). In space, the satellite cannot just stop and wait for a tow truck to arrive. - there is only one satellite to test the update on. If they screw it up, it's gone. With cars, there are many to test on, so errors will turn up and be fixed faster. But back to the issue of risk: Just like with drunk driving, you are at risk of somebody else's car going haywire as well, so it's a risk regardless of whether you yourself updated or not. At that point, the difference between your existing risk and the risk you take on from the update is probably not that great, so might as well just do the update.
